LIQUID MORDANT FOR USE IN DYEING- FABRICS.

No Drawing.

I fabrlos and its object is to provide what I term a liquid mordant to be used in the dye solution during the process of dyeing fabrics, and whereby the dye colors will be fixed during the dyeing process and will be rendered fast and permanent, and which will enable faded fabrics to be dyed a uniform color so that both the faded and unfaded portions of the fabric will have the same color when the dyeing is completed.

The present invention therefore includes such liquid mordant and the method of preparing the same, and the following description will enable others skilled in the art to make the liquid mordant and use the same. i The method of making the liquid mor-' dant is as follows:

I place a quantity of sodium chlorid or common salt in a suitable percolating vessel or container, through which water can percolate, and which may be of any desired or convenient suitable kind or construction.

Then dissolve sodium sulfid and naphthalene in hot water and after thoroughly mixing them, pour the mixture, preferably while boiling hot, over the sodium chlorid in the percolating vessel, and the hot mixture percolates through the sodium chlorid, and takes up part thereo'f and the percolated liquid is collected in a suitable receiver and constitutes the liquid mordant.

In making the liquid mordant I preferably. use the following proportions of ingredients:thirty (30) pounds of sodium chlorid; two (2) gallons of water; two 2; pounds of sodium sulfid; and one 1 pound of naphthalene.

The said liquid mordant is composed of a hydrated solution of sodium chlorid, sodium sulfid, and naphthalene, produced under the influence of heat.

This liquid mordant is very useful in the process of dyeing and is effectively used as follows:

ment or fabric he adds some of this mordant to the water for the dye, then adds the dye thereto, then boils the garment or fabric in the mixture of liquid mordant dye and water; and afterward washes the dyed fabric in clear water and drys it.

The proportion of liquid mordant used in dyeing may vary,but good practical results are obtained byusing one fluid ounce of the liquid mordant to five gallons of dye water.

By the use of this liquid mordant, as described, faded garments can be dyed any color, blue, green, violet, brown, etc.; and by use of this liquid mordant partly faded fabrics, or garments faded on the shoulders, collar, lapels, etc., which heretofore could only be dyed black (as other colors would not dye even, that is, the color of the faded parts of the fabric or garment when dyed in colors would be different in shade from the unfaded parts) can be dyed a uniform shade throughout.

Having described my invention what I claim is:

1. A composition for use in dyeing, containing sodium sulfid, naphthalene and sodium chlorid, substantially as described.

2. A mixture for use in dyeing comprising water, sodium sulfid, naphthalene and sodium chlorid, substantially as described.

3. A liquid for use in dyeing fabrics, obtained by subjecting sodium chlorid to the action of a mixture of water, sodium sulfid and naphthalene.

4. A liquid for use in dyeing, obtained by passing a hot mixture of water, sodium sulfid and naphthalene through sodium chlorid.

5. A liquid for use in dyeing fabrics obtained by percolating a hot mixture of water, sodium sulfid and naphthalene ;in substantially the proportions of one pound of naphthalene, two pounds of sodium sulfid and two gallons of water ;-through a mass of substantially thirty pounds of sodium chlorid.

6. The herein described process of male ing a liquid for use in dyeing, consisting in passing a mixture of water, sodium sulfid and naphthalene through sodium chlorid and collecting the resultant liquid.

7. The herein described process of making a liquid for use in dyeing consisting in percolating a heated mixture of water, so-

dium sulfid and naphthalene While hot through a mass of sodium chlorid and collecting the resultant liquid.

8. The herein described process of making a liquid for use in dyeing consisting in heating Water, sodium sulfid and naphthalene and then letting the mixture pereolate through a mass of sodium chlorid and collooting the resultant liquid.

9. The herein described process of making a liquid mordant for use in dyeing, consisting in mixing Water, sodium sulfid and naphthalene, in substantially the proportions of one pound of naphthalene, two pounds of sodium sulfid and two gallons of Water; and then letting the same percolate pounds of sodium chlorid and collecting the resultant liquid.

In testimony that I claim the foregoing as my own, I aflix my signature.
